BGOKBINDZNG nracrrrnn Application filed March This invention relates toan improved ma chine for fixing covers to stitched or sewn copies ofmagazines, pamphlets, catalogues, booklets and the like. invention thework to be bound is placed in a carriage mounted to run or slide on ahorizontal support, the book being held in such manner near the backedge that said edge is fully exposed below the carriage or otherwise.lifeehanism is provided for moving the book and carriage forward over aroller which is revolved in li uid lue to 7,

whereby glue is applied to the back of the book. The book is thenbrought over a pile of covers which is moved upwards mechanically,causing the top cover of the pile to adhere to the glued back portion ofthe book. After this operation the book with the cover attached is thentransferred to another carriage automatically, the second carriageengaging the book and carrying it forward for a further operation oropera tions whilst the first carriage is automatically andsimultaneously released and travels back to its first position. lVhilstbeing held on the second carriage, the book is acted upon by a suitableroller or rollers adapted to apply pressure along the back and along theside portions of the book adjacent to the back, means being alsoprovided for closing the covers after the rolling operation.

The book then falls or is delivered from the carriage and slides down aninclined table into a hopper or on to a revolving band or tape conveyorwhich carries the book forward and deposits it where required.

Itwill be understood that provision is made for the adjustment of themechanism in accordance with the varying thickness of the back of thehook and also the varying sizes.

The invention is with reference to the accompanying drawings in which;

i rccording to this hereinafter described" Serial No. 627,925.

12 and 13 illustrate the feed regulating mechanism in plan, the planbeing separated into two figures for the sake of clearness,

Figs. 1a and 15 are longitudinal and transverse sections of the glueingapparatus,

Figs. 16 and 17 are side and end elevation respectively of the mechanismfor pressing the cover against the back and sides of the book.

In the practical form of construction illustrated in the drawings, theframe of the machine, which may be built up or cast in one piece,comprises a base member a abovewhich at a convenient height and towardsthe rear side of the machine is supported a horizontal guide member andsupport 6 for two oppositely reciprocating trav elling grippers orcarriages 0 0 in which the book is held successively as it passes fromthe feed to the delivery end of the machine. On the front face of thehorizontal guide member two horizontal dovetail guides, bars or ribs d,d are provided and enga 'e guide grooves of corresponding shape in thetravelling grippers or carriages which are adapted to slide freelythereon in front of the guide member or carrier 6. As shown the twodovetail guides d, al one for ping jaw e each carriage run from oppositeends of the machine and overlap at the middle over the place where thepile of covers is supported and where the books are transferred from onecarriage to the other, the carriage guide (Z running from the feed endbeing at a higher level than the carriage guide CZ run' ning from thedelivery end of the machine.

Each carriage or travellinggripper has a pair of overhanging verticaljaws e, 0 between which the books are gripped and held parallel with thepath of movement of the carriage with the back downwards anc exposedbelow the carriage. One jaw c, f of each pair is mounted to slide onguides at right angles relatively to the other jaw c 7" and is actuatedautomatically to grip the book placed between the jaws when the carriageis about to begin its movement in one direction and to release the bookwhen the reverse movement of the carriage begins, by a suitably shapedcam g or 9 carried on a rock shaft Zr or h on the carriage and engagingbetween a pair of collars 2' or z" or in a grooved boss on a spindle orrod 7' or j connected with the relatively movable grips moved endwise bythe action of the cam. The jaw actuating spindle j or is alsoscrew-threaded and runs through a screwthreaded aperture or nut 72 or 76on the jaw so that by rotating the spindle through a suitable handle Zor Z on the disks Z or Z carried by the spindle or 7" the gripping andrelease positions of the jaw can be adjusted recording to the thicknessof the books to be held. For positioning the back of the book at thecorrect level in the feed carriage a table m is adjustably mounted onthe framing at the feed end of the machine below the gripping jaws ofthe carriage.

A positioning gauge stop a for the book is also arranged to extendacross the inner ends of the gripping jaws c, c of the feed carriage cand is carried on spring pressed arms n pivoted on the jaw e, the stopit being moved into operative position against the action of the springa by a rail a fixed to the frame of the machine at the feed end in thepath of a roller a on the stop arm at. forward advance of the carriagethe spring a removes the stop out of the way so that it shall notinterfere with the transference of the book from one carriage to theother.

7 pins 0, 0 carried on a The two carriages c, c are caused to travelsimultaneously from the opposite ends of the machine to the middle andback again by lever mechanism actuated by crank pair of intermeshinggear wheels 0 0 driven by a suitable .motor 0 on the machine or bybelting from a power shaft. The gear wheels 0 0 are or f and capable ofbeing,

adhering- When the roller leaves the rail on the keyed on shafts 27, pmounted to rotate in bearings on the base of the machine and their crankpins 0, 0 are connected by rods 0, 0" ,with levers 0 fulcrumed on thebase of the machine and having long upwardly extending lever arms 0, 0which are linked by spring links {[5 g to arms 72, Zr on the rockingshafts Zr, h of the carriagesin such manner that not only is the travelof the carr s effected but the gripping jaws of the carriages areoperated at each reverse movement of the carriage to open or close asnecessary by the actuation of the rocking shafts it, h and the cams gcontrolling the opening and closing movements of the jaws.

In order to ensure that the carriages shall register correctly for thetransference of the books from one carriage to the other, stop plates'2, r are provided on the car riages and come against gauging stops 9,and r on the frame.

it the middle of the machine below the overlapping portions of thecarriage guides (Z, (Z the pile of book covers 8 Figs. 1 and 11 issupported on a vertically movable table 8 adapted to press the top coverof the pile against the back of the book and actuated by a cam 27carried on the gear wheel 0 and timed to lift the table when the book isbrought over same. The cam acts on a lever 32 arranged to operate arocking shaft 12* provided with two arms 2), 7; one of which 27 engagesa collar or projection s on a vertically displaceable rod or bar 8 onwhich the table is supported, the table proper being adjustablysupported by screw-threaded spindles 8*, 8* above a cross-head s fixedto the vertically displaceable rod or bar 8 aforesaid. It willunderstood that after the table has been lifted by the cam 22 asdescribed to apply the cover to the book, it is lowered again by its ownweight, a counterweight p carried by the arm 72 for this purpose. Thetopmost cover is thus left to the back of the book to which a suitableadhesive has been previously applied, and this movement of the tablewhich constitutes in effect a vertical reciprocating movement isrepeated as the different books are successively brought into positionover the table.

In order to compensate for the gradual decrease in the depth of the pileof covers on the table it is necessary to" impart to the table inaddition to the reciprocating movement aforesaid progressive upward feedmovement for which purpose the screw spindles s which support the tableproper pass through two nuts t arranged in the crosshead a aforesaid andgeared together by chain and sprocket gear 6. One of the nuts is formedwith ratchet teeth with which a feed pawl t engages, the pawl be ingpivotally supported on an arm 25 on a vertical shaft- 6 and pulled intoengagement by a spring Z oscillating motion is imparted to the verticalshaft to actuate the feed pawl by a cam. on the drivirg gear wheelhereinbefore described, operating on a lever arm i on the shaft whichafter being displaced by the cam is returned by the spring i The pawlshaft t is divided into two parts connected by a sleeve or coupling 21*which permits the upper part to partake of the vertical movement of thetable .9

without becoming disconnected from the lower part. (living to variationsin the thickness of the covers employed, it sometimes becomes necessaryto vary the upward feed of the table a, and provision is made forautomatically controlling the operation of the feed pawl Z to regulatethe upward feed of the pile of covers according to requirements by adevice which prevents the pawl from engaging the ratchetteeth 6 when itis desired to check the feed. A feeler or finger u Figs. 11 air 12resting on the top of the pile of covers 8, is connected through levermechanism a, a rod a, le vers a if and rod u with a pivoted plate Fig.13, mounted on a bracket u and carrying a spring controlled arm to whichis moved into the path of a pin c on the feed pawl t where the arm itbears against an inclined projection c on the bracket to and preventsengagement of the pawl t with the ratchet teeth of the nut when thefeeding is to be checked. Means are also provided for maintaining theregulating device in the operative position until the pawl has clearedthe ratchet tooth, consisting ot a notched catch lever 11 which engagesa nose c on the pivoted rocking plate, and released at the completion ofthe return movement of the rocking arm i carrying the pawl t by a pin '0on that arm.

Fixed in the frame below the path of the books and in advance of thetable on which the covers are supported, is a glueing apparatuscomprising a roller 10 rotated by suitable gear 10 fron'i the main gearshaft and partly immersed in a glue receptacle 10 mounted in a watertank in heated by a gas or other suitable burner 10. The backs of thebooks run over the glue roller as they pass to the position forreceiving the covers. A free or driven roller :0 for pressing the coveragainst the back of the book and also applying pressure along the sideportions adjacent to the back is resiliently supported by the lever armsa pivoted on brackets on the main frame adjacent to the table from whichthe covers are taken. End flanges x x are provided on the roller whichengage the side portions of the cover adjacent to the back one of theflange m having a split screw-threaded sleeve and clamping nut so foradjustably securing it on the roller whilst the other flange is loosebut is held against the roller by a helical spring 00 on the rollershaft.

By mounting the flanges in the manner described the roller can beadjusted to take books of different thickness and can readily adaptitself to slight variations or irregularities of the back of the book.Means are also provided for depressing the roller momentarily as thebook moves on to it to prevent undesired creasing of the leading edge ofthe cover as it enters between the flanges of the roller. For thispurpose the arm 3) on the cam operated rock shaft 30* hereinl oforereferred to is arranged to depress a vertically guided rod 2 which isco: necied at its upper end by link y with one ot the supporting arms 5;of the pressure roller a: and pulls the roller downwards against theaction of a spring, permitting the leading edge of the book to come overthe flanges of the roller without obstruction.

The book is drawn over the pressing roll or by the second carriage andthen released at the point of discharge through the automatic opening ofthe gripping jaws and falls between a pair of cover folding bars a, onto an inclined delivery table a.

This table is pivoted in the framing of the machine and in the operativeposition lies under the carriage in the path of the operating leverwhich however, is arranged to bearagainst an inclined edge on the tableto move it out of the way as the lever springs forward.

In some cases the discharge of the books from the carriage is assistedby a plunger plate a supported by parallel links 2 from bracket 2 on themain frame and actuated through lever mechanism 2 from the operatinglever of the carriage.
